Be it known that I, NELs P. TANGWALL, citizen of the United States, residing at Duluth, in the county of StLouis and State of Minnesota, have invented certain new and useful Improvements in Portable Shears, of which the following is a; specification, reference being had therein to the accompanying drawing. i

This invention relates to certain improvements in shears and has specialreference to portable hand shears for cutting metal.

The principal object is to provide a convenient form of such shears for shop use and one having supporting means w'lnch may be employed for other purposes if de sired.

Other objects and advantages of the invention will appear in the further description thereof. 5

Referring to the accompanyingdrawings forming part of this application and in;

which like reference characters indicate like parts:

-Figure 1 is a side elevation of one of my 1 I improved shears.

Fig. 2 is a sectional View taken on the line 22, Fig. 1, showing the holding means in elevation.

F ig. 3 is a section on the lineB-S, Fig. 2, and

Fig. 4 is an elevation of a fragmental portion of the body of the shears.

1 represents the body portion of the shears the-upper end of which terminates 1n the extended cutting'jaw 2 upon one side and an extension 3 upon the opposite side, in which latter is formed a plurality of different sized holes 1 in which round iron or wire may be cut The lower part of the body portion 1 has an extension 5 thereupon and formed at right-angles thereto, this extension being primarily for engagement with the table or bench upon which the shears are placed. 7

The body portion 1 has a vertically d1s-' posed channel or recess formed therein, the bottom ofwhich is serrated or toothed-asat 6 said channel being formed through the baseof the extension or jaw 5 and adapted to receive the complementally toothed shank V 7 which forms a longitudinally disposed extension of the body 1. The lower'end of the extension 7 is turned at right angles thereto forming a support 8 for the manually operative screw 9, the upper end of Application filed september G,'1919.'-Seria1N0, 322,046,

s cime t I Patented t me s, 1920 which carries as aw 1b which rarin the lowermost memjber of the clamping 'ineans for supporting the shears 1 upon 'a table, bench or the :like." The lower body portion of-the extension 7 is centrally slotted as at 11 providing a guide fortheinner end of the 10 which extends therein and prevents the-latter from turning with the screw 9, the e'Xtreme-mnerendof said jaw be yond the shank 7 bein g 'reduced andflpro shown at "The shank 7 'i is held in any predetermined position in the channel by a suitable bolt 19 and wedge 20 there being vided with a 'suitable 'washerand nut as a slot 21 in the center of the channel to accommodate such adjustment.

In having a second jaw corresponding in s ze and extent to the jaw 5 and made reclprocably carried upon the screw 9, I have provided a convenientfportable vise which may be of. considerable service when the,

shears are not being used.

At 13 I have shown pivotally mounted the upper member or jaw 14 of thefshears which co-acts in the process of cutting with the aw 2 and the holes l alternately, said member 14 being provided with-a suitable rigid handle 15 for manipulating same.

As a gage for cutting either rods or plate a given predetermined length, I have formed a laterally projecting hub 16 upon i the lower jaw member of the shears and through which hub is longitudinally adjustably mounted a rod 17 carrying an arm 18 upon one end thereof and which arm may be placed any desired distance from the shears within the limits of I the length of the rod 17 it being possible to swing the arm 18 either opposite any one of the holes 4 or opposite the cutting shears to act as suchgage.

From the foregoing it is evident that I have devised a convenient combination tool for the purpose intended and while I have shown one specific embodiment of same it with the fixed jaw. j 2. A tool support of the character described comprising an upright body portion having ajaw extending, laterally therefrom,

ried by said body portion, a laterally extending fixed jaw carried by the body portion, a manually operated screw carried in the lower end of the extension and aisecond jaw carried upon the screw, and slidable within the extension for cooperative action a recessed channel within the .face of the body portion from which the jaw extends V and passing through the base of the jaw,

an extension slidably mounted within the channel and carrying a vertically adjustable screw in its lowermost angular end, and a second jaw slidable within the extension and carried upon the end of the screw for coaction with the fixed jaw.

A clamping and holding device of the character. described comprising in combinaing anvangular jaw formed integral therewith, a second slotted body portion slidable through the jaw of the principal body por- "tion and having'a fixed jaw at the outer termination thereof, said fixedjaw being parallelland in line with the first mentioned jaw, a third j awjslidably carried upon the second body portion and reciprocable intermediate of the first andxsecond jaws, means,

tion a principal slotted bodygportion hav- 7 carried by the latter for such reciprocation and means for holding the two body por V 'tions rigidly united, substantially as de- S. GEO.'STEVENS.
